WlCK-RAISING DEVICE FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 510,379, dated December5, 1893.

Application filed March 13, 1893- Serial No. 465,719. (No model.)

T0 at whom it may concern.-

Be it known that I, REINHOLD BRENNER, a citizen of the United States,residing at- Waterbury, in the county of New Haven and State ofConnecticut, have invented certain new and usefullmprovements inWick-Raising Devices for Central-Draft Lamps; and 1 do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has for its object to simplify and cheapen the constructionof wick raising devices for central draft lamps while at the same timetheir operation in use shall be greatly improved for the reason that thenumber of parts is reduced to a single one, and that power is applied tothe carrier itself, not to intermediate parts, in raisingor lowering thewick. It is of course understood by those familiar with the art that therequirements in a device of this class are that it shall be inexpensiveto produce, easy to operate, positive in its action, so constructed asto make it easy to remove and replace the wick, and practicallyimpossible to get out of repair. In order to accomplish these results inthe simplest and least expensive manner possible I have devised thenovel wick raising device of which the following description inconnection with the accompanying drawings is a specification, numbersbeing used to indicate the several parts.

Figure 1 is a section of a portion of a lamp reservoir or fount showingmy novel wick raising device in side elevation the wick carrier and wickbeing at the extreme lowered position; Fig. 2 a similar view the wickcarrier and wick being at the extreme raised position so that the wickis free to be lifted off from the carrier, and Fig. 3 is a section onthe line :1: co in Fig. 1 looking down.

1 denotes the reservoir or fount of a lamp and 2 the central tube whichserves as an inner air supply and also as a support for the wick 3 whichin use slides freely over it.

A denotes the wick carrier as a whole. This Wick carrier in practice ispreferably made from a single piece of wire the ends of which are curvedto partially inclose the tube and constitute jaws 4:which arepreferablyprovided with prongs 5 to enable them to grasp the wick firmly.Thecent-ral portion of the piece of wire from which the jaws are madeconstitutes a shank 6 which extends downward from the jaws then outwardand upward through a bearing sleeve 7 in the top of the reservoir orfount, the upper end of the shank being bent outward at an angle to forma lifting piece 8 for convenience in operation. 9 is a clasp which mayor may not be used at the lower end of the shank. In practice I usespring wire so that the jaws will grasp the tube firmly through theresiliency of the metal from which they are formed.

In connection with my novel wick carrierI provide the central tube withan annular groove or channel 10.

The operation is as follows: Suppose it is desired to wick or to re-wickthe lamp. The wick carrier is raised until the jaws lie in groove 10,the resiliency or spring action of the jaws causing them to drop intothe groove as soon as they reach it. In this position the externaldiameter, that is the transverse diameter from side to side, is butlittle if any greater than the external diameter of the main portion ofthe tube so that the prongs will take very little hold upon the wick andwill allow a wick to be readily removed and a new one slipped on overthe jaws and tube and down to place, the lower portion of shank 6servingas astop to prevent the Wick from dropping down too far under anycircumstances whatever. The operator having placed the new wick inposition pushes the carrier down from the position shown in Fig. 2toward that shown in Fig. 1. As soon as the jaws are forced out fromgroove 10 the wick will be distended thereby and the prongs will beforced into the wick from the inner side so that when the carrier ismoved up or down over the surface of the tube the wick will be carriedthereby and can only be removed from the carrier when it has been drawnup high enough so that the jaws will pass into the groove. In the latterposition the wick is released from the jaws and may be readily removed.

Having thus described my invention, I claim- 1. In a central draft lampthe combination with an air tube having an annular groove, of a wickcarrier consisting of jaws which embrace the tube and engage the Wickfrom the inner side, and a shank made integral therewith by which thecarrier and wick are moved.

2. The combination with a central tube having an annular groove 10, of awick carrier consisting of spring jaws embracing said tube and adaptedto pass into the groove, and a shank by which the jaws and wick areraised or lowered, the wick being held firmly by the jaws from the innerside except when the jaws are in the groove at which time the wick isfree to be removed.

3. The wick carrier comprising spring jaws, and the shank by which theyare raised in' combination with a central tube having an annular grooveadapted to receive the jaws,

20 said jaws engaging the wick from the inner side and holding it firmlywhen forced downward out of the groove and leaving the wick free to beremoved when moved up into the groove.

4. The wick carrier comprising curved spring jaws having prongs upontheir outer sides and a shank which is curved downward and then upwardand serves as a stop for the wick, in combination with acentral tubehaving an annular groove into which the jaws are adapted to pass whenthe wick carrier is raised to its highest point thereby releasing thewick and leaving it free to be removed.

In testimony whereof I affix my signature in presence of two witnesses.

REINHOLD BRENNER.
